Hi,
I have just finished building an Arduino ambilight setup using a nano.
During the construction, whilst trying to upload the software, I rebooted my nano using its power supply. Upon trying to power it again, my computer said DEVICE NOT RECOGNISED.
I was irritated, but put it off as a faulty board. I happened to have another board, so after finishing the ambilight construction I uploaded the relevant software and all was working great.
I came to turn it on again and the computer was unable to recognise it. The same as the other arduino. I now was sure it wasn't a faulty board as it had worked initially.
I have tried uploading a simple sketch after pressing the reset button... to no avail.
I have checked the drivers are correct, swapped the cables and also reinstalled the arduino software.
Has anyone got any idea what this is and how I can fix it?! It's getting expensive!
Cheers Alex
